However, while fixing the car's gasoline engine, Jin Xiaoqiang also considered the problem of switching to another fuel for this car.

The reason why Mazda's two Chuangchi Blue Sky technology engines are awesome is not only that they can achieve the combustion ratio of the old 1, but also a very important point is the car's engine's ability to adapt to fuel.[]

You must know that general in-cylinder direct injection engines have very high fuel specification requirements.

For example, the ecoboost engine currently invented by Jin Xiaoqiang and the others. The key reason why this engine can reach an air-fuel ratio of 15:1 is that the nozzle used for direct injection in the cylinder is able to inject more energy than a human can.

A mixture of oil mist that is as thin as hair.

But in this way, employment also means that the gasoline specifications of this engine will be particularly high. Abroad, it needs to add 97 gasoline, but in China, because of the leadership of Tianchao Petroleum and Petrochemical, it has to drink Maotai and Lafite.

relationship, so progress in petroleum refining has not been great. The current highest grade gasoline in China is No. 95, and although it is No. 95, its specifications are similar to those of foreign No. 93 gasoline.

Therefore, Jin Xiaoqiang and others had to lower the standard of the in-cylinder direct injection nozzles of domestic ecoboost engines, because if they did not do this, they would face the problem of nozzle clogging over time.

In this way, the air-fuel ratio that this engine can achieve when using domestic gasoline is about 13:1. Although it cannot be compared with the ones they buy abroad, this is also due to the limitations of practical conditions.

It's not that they want to discriminate.

But currently there are very few cars in China that can achieve an air-fuel ratio of 13:1!

When it comes to adapting to various types of fuel, Mazda's Chuangchi Blue Sky technology engine is undoubtedly a model.

The in-cylinder nozzle used by this engine is a six-hole nozzle, which makes it more adaptable to various types of gasoline. Although it cannot do the same thing as the nozzle of the ecoboost engine, which can spray five minutes of human hair.

A finer oil mist, but it can spray more oil.

Therefore, the nozzle of this engine has better adaptability to fuel.

However, the nozzle technology currently used by Jin Xiaoqiang is provided by Bosch. Currently, it can only produce four-hole nozzles. If it wants to produce six-hole nozzles, it will require more technical adjustments.

But because they have already obtained two fine grinders from Bosch for grinding the nozzle parts, it is not too difficult to complete the grinding of the six-hole nozzle. They only need to make corresponding modifications to the couple parts.

Done.

Jin Xiaoqiang even wondered whether to replace the ecoboost engine with such a nozzle once the six-hole nozzle grinding is completed. In this way, he would like to see if the air-fuel ratio of this engine will be better.

improvement.

Although the engine of Mazda's Skyline uses a six-hole injection nozzle, its ability to adapt to gasoline specifications is truly unparalleled.

Jin Xiaoqiang remembers clearly that at present, engines using in-cylinder direct injection technology have very high fuel specifications, even in foreign countries. This is why so far, in-cylinder direct injection technology has not been widely popularized.

The main reason for coming.

Low-standard gasoline has many internal impurities. When in-cylinder direct injection technology encounters such gasoline, the problem of nozzle clogging will often occur after tens of thousands of kilometers of travel.

Mazda's engine can fully adapt to this. I remember in my last life, this engine worked just as well even with No. 87 gasoline abroad. Of course, other people's No. 8 gasoline must be equivalent to domestic gasoline.

92# or 93# gasoline.

This will bring an advantage to this engine, that is, it will work equally well even when using methanol gasoline.

In fact, Jin Xiaoqiang has long been considering the issue of using methanol gasoline. As we all know, methanol gasoline is actually a mixture of methanol and degasoline in a ratio of 4:1, and just add a little corrosion inhibitor.

Because the thermal efficiency ratio of methanol is lower than that of gasoline, which can only reach about 45% of gasoline, it will be more difficult to start a car with pure methanol when the weather is cold, so gasoline and methanol must be mixed to a certain extent.

Only then will a more ideal effect be achieved.

And because methanol has a low thermal efficiency ratio, if you want to achieve the same effect as gasoline, you must increase the injection volume of methanol, and this six-hole nozzle can exactly achieve this effect.

Methanol gasoline actually appeared during World War II. Due to the shortage of oil, the Germans began to research a new type of fuel, which was actually methanol obtained by using coal hydrogenation technology.

However, during World War II, this type of fuel was not promoted on a large scale because methanol fuel would corrode rubber oil pipes and cause damage to fuel tanks.

However, with the development of industrial technology, today's cars no longer use rubber hoses as oil pipelines, and the materials used in fuel tanks have also been greatly improved than before. Therefore, methanol corrodes the rubber soft

It can be said that problems such as management have long since ceased to exist.

The reason why it has not been widely popularized in the past is simply because the supply and demand for oil around the world were not particularly tight before. However, after the oil crisis in the 1970s, Americans and Japanese

We have already started researching this methanol gasoline.

Now in the United States and Japan, a considerable number of large trucks and buses use methanol gasoline, so this technology can be said to be quite mature.

What Jin Xiaoqiang firmly believes is that as oil prices rise day by day, methanol gasoline should have a broader market in China. After all, our coal resources are too abundant.

Moreover, using methanol gasoline has another advantage, that is, it can clean the oil circuit. As we all know, after a car has traveled tens of thousands of kilometers, sticky attachments and carbon deposits will often appear on the oil circuit. However, using methanol gasoline can easily clean the oil circuit.

Proper cleaning of these magazines and carbon deposits is of great benefit to cleaning the car's oil lines and cylinders.

So if you want this car to be able to burn methanol gasoline at the same time, you only need to set the EC of the car

Make certain adjustments above u and install a control switch in the car.

After the car is filled with methanol fuel, as long as the pressure of the booster pump is increased, it can inject more methanol fuel, which can achieve the same effect as burning gasoline.

Moreover, methanol gasoline has better anti-knock properties due to its high octane content, which will further enhance the smooth driving and noise control of the car.

The most important thing is that if methanol fuel is used, the fuel consumption of the entire vehicle will be about half lower than that of gasoline.

Jin Xiaoqiang believes that as long as this gimmick is brought out, it will definitely become a big selling point. Although not everyone can accept methanol gasoline, after all, methanol is poisonous, but this gimmick can still be considered and hyped up.

, after all, oil prices are too high, but this has been an issue that has attracted much attention in China in the past few years.

However, this is still a preliminary idea that is not too mature yet. At present, it cannot be verified to a certain extent before this engine is born.

The relationship between a car's engine and transmission is like a person's strong heart and strong muscles.

If you have a strong heart, but do not have strong muscles, then this person will also be unable to move as he pleases.

Now Jin Xiaoqiang has invited a makeup master Peter Richier to give this K series a beautiful appearance, and he himself has designed a strong heart for this car, so what happens next?

The first step is to add strong muscles to this car, that is, a transmission with stable performance.

For this car, because it is positioned higher than the Eado but lower than the Qoros series, this car must have a bright spot in terms of transmission.

In fact, Jin Xiaoqiang didn't need to think too much. All he had to do was take the transmission that Mazda originally equipped for this series of cars.

Mazda's transmission in Chuangchi Blue Sky technology is just a 6at transmission. Although it is also a hydraulic transmission, the effect of this transmission is very ideal. It can even improve the fuel consumption of this transmission.

, comparable to a manual transmission.

The secret is just that a lock-up clutch device is installed on this hydraulic transmission.

As we all know, the power loss of a hydraulic automatic transmission is mainly in the hydraulic torque converter that transmits power while buffering the impact of shifting. The principle of the lock-up clutch is actually that the hydraulic torque converter is equivalent to two sets of fans, and the lock-up clutch

The clutch is equivalent to some bolts holding the two sets of fans together.

That is to say, after the nose shift is completed, the hydraulic torque converter is locked. At this time, it is equivalent to a hard connection between the engine and the transmission gear set. In this way, the transmission efficiency of the hydraulic transmission can be equal to that of a manual transmission.

Such a small change may be a mediocre invention in a few years, but now, it is a very remarkable idea.

You must know that the currently popular hydraulic automatic transmissions on the market are only five-speed automatic transmissions. Six-speed automatic transmissions can only be equipped on high-end models and have not been widely popularized. However, if this is used at this time,

Once the technology is revealed, it will definitely be an amazing invention!!
